My computer boots to a black screen, what options do I have to fix it?
I am fairly new to Ubuntu, but love it already.
I recently went into grub and switched back forth between integrated and discrete (nvidia) graphics and now when I boot using the integrated card I get to ubuntu's purple page and then after that the screen goes black and nothing.
I may have accidentally modified some file while trying to follow some advice online, but not sure what files. Maybe "/etc/X11/xorg.conf" but I'm not sure and if so I can't remember what I did to it.
What can I do to get it working again?!?!?
UPDATE: I wanted to add a little more information about my system
- Computer: Lenovo Thinkpad W520
- System: Ubuntu 11.04
- Processor: Intel Core i7-2820QM Processor (2.30GHz, 8MB L3)
- System graphics: NVIDIA Quadro 2000M Graphics with 2GB DDR3 Memory
- Total memory: 16 GB PC3-10600 DDR3 SDRAM 1333MHz SODIMM Memory (4 DIMM)
Thanks!
